Summary. – Pseudemys concinna (Family Emydidae) is a large, riverine turtle that occurs in relatively dense populations throughout the eastern and southern parts of the United States. Currently generally recognized subspecies include P. c. concinna and P. c. suwanniensis. Studies of diet, reproduction, and population demography have focused chiefly on Florida populations. There is little reason to be concerned about the species’ survival, although no definitive studies have been conducted to establish population dynamics or statistics across its entire distribution. Further study is necessary to determine whether specific protective measures beyond those already in place in some states are needed.

Red points = museum and literature occurrence records based on Iverson (1992) plus more recent and authors’ data; green shading = projected distribution based on GIS-defined hydrologic unit compartments (HUCs) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al., unpubl. data), and adjusted based on authors’ data.
